Introduction

1. Background of standard formulation and analysis of technological evolution

GB/T 25423-2023 "Square Baler" is a comprehensive revision of GB/T25423-2010, mainly targeting the development needs of agricultural machinery. The new standard introduces a number of technical improvements, including new term definitions, optimized product model representation methods, and strengthened safety requirements.

2. Comparative analysis of standard frameworks

Dimensions	Old standard (GB/T25423-2010)	New standard (GB/T 25423-2023)
Definition of terms	17 terms	Increased to 35 terms, with new definitions such as cutting and kneading devices
Performance indicators	The classification of small, medium and large is not clear	Different performance requirements are formulated according to the size of the machine
Safety specifications	Basic safety requirements	Detailed safety regulations for new protective covers, automatic lubrication systems, etc.

3. Technical requirements interpretation

Material selection and processing: All parts must meet the mechanical performance requirements, and castings and forgings must be free of defects such as cracks and sand holes.

Actual application case

A certain agricultural machinery factory uses the new standard to produce large square straw bale balers. By optimizing the design of the cutting and kneading device, the straw bale density and bale rate are significantly improved.

4. Safety requirements and implementation suggestions

Safety signs: Safety warning signs are set in obvious locations to ensure that operators can clearly identify dangerous areas.
Maintenance: Regularly check the lubrication system and electrical components to extend the service life of the equipment.
Training: Provide professional training to operators to ensure the correct use and maintenance of equipment.
